New sea lamprey barrier protects Lake Ontario fishery

A new sea lamprey barrier in New York’s Orwell Brook will reduce the number of those deadly invaders in Lake Ontario and decrease the use of chemical lampricides, lowering the cost of controlling the sea lamprey population.

A single female lamprey can produce 100,000 eggs and a single adult lamprey can kill up to 40 pounds of fish annually. The barrier was funded by the Great Lakes Fishery Commission, which spends about $20 million annually to control sea lamprey populations in all five Great Lakes. Read more here.
